eMOLT Update 2024-04-19
Weekly Recap
Huanxin is this week’s MVP
Huanxin has been working hard on migrating all of the data generated
by the realtime eMOLT program over the years from our old servers to our
new cloud infrastructure. This migration is necessary to ensure all of
the eMOLT data are stored in a standardized, accessible way so that we
can respond quickly to data requests from stock assessment scientists,
forecasters, and the fishing industry. However, like any major change,
there are often growing pains. In this case, a strangely formatted file
in the mix put enough sand in the gears to stall out our new ERDDAP
server. So if you’ve noticed a lack of new data there, that’s why.
Huanxin also spent a few days in JiM’s basement working together to
conduct calibration checks on Minilog temperature probes. This is an
operation that JiM has conducted nearly every year since eMOLT began
where dozens of probes are exposed to a range of temperatures (0-20
degC) similar to that experienced in the Gulf of Maine. For the last
several years, the probes have been compared to a highly accurate (0.001
degC) Fluke temperature sensor. As seen in the graphic below, a) the
pump is critical to provide a well-mixed bath, b) the time response of
the Fluke thermistor is much faster than the Minilogs, and c) the mean
difference between the Fluke and Minilog probes was ~0.1 degC after
waiting for the response.

If you participate in the non-realtime program, you should be
receiving your probe in the mail soon. If you don’t, please reach out to
George by calling / texting 508-299-9693 or emailing george.maynard@noaa.gov and we’ll get it sorted
out.

This Week in Red Tape
In a true to form moment for the government, we were asked to update
eMOLT’s online presence to include new phrasing mandated by the
ironically named Paperwork Reduction Act. The old emolt.org site and new
ERDDAP server where we make the data available to ocean forecasters are
now in compliance with the PRA, so we can all rest easy at night.
Notes from up North
We welcomed a new boat and crew to the program this week. Erin and
Emma hopped aboard the F/V Gladys Elaine yesterday to install a new Deck
Data Hub and hand off two Moana sensors to Capt. Pete, a longtime
participant in the non-realtime eMOLT program.

Going back through my notes from last week’s cyberinfrastructure
workshop in Portsmouth, one quote from a speaker stood out to me.
“Standards are like toothbrushes. Everyone wants one, but nobody
wants to use anyone else’s”
I guess the analogy isn’t perfect, because we are slowly working to
get everyone to use the same toothbrush…gross, but efficient? As we
collaborate with the software engineers at Lowell Instruments on the new
version of DDH software, we’re ensuring that the data collected on your
deckboxes will adhere to international standards, so the data collected
here in the Northeast USA can be interoperable with other, complimentary
datasets like the deep sea Argo float data, or fishing vessel collected
environmental data from elsewhere in the world. This interoperability
means that more researchers around the world will be able to make use of
eMOLT data in their research, increasing the value of the work you’re
all doing, and cementing eMOLT’s role as a global leader in this
space.
